I have a 2004 f-150 w/audiophile. Does anyone know which wires (color) in the factory harness are for the following:

Constant power
Switched power - on & off with ignition
ground

 

according to my alldata.com account, which I recommend getting, there are different color wires for the different models.

VPWR which is the switch is Red/Black on all plus:
Light Green/Yellow for XLT, FX4, Lariat
Pink/Black for XL, STX

VBATT which is always hot is Light Green/Violet

and ground is Black/Light Green and Black

understand that color/color means striped.

Hope that helps.
